As you can see, there are some pretty important commands in this list. And this is just a small sample of them. On my AIX server I found that there are over 400 scripts included as part of base AIX! You can see a full list of all the scripts that make up your system by running a command like this:

It is pretty cool that so many of the core commands/utilities on AIX are made up of shell scripts. For one, it shows that shell scripts can take on very important and critical tasks. It can also be extremely helpful to be able to review the scripts if you are having any issues with any of these commands. And these scripts can be an excellent learning tool. These are extremely well written and robust scripts many of which have been used for decades on thousands and thousands of servers.
